Composite component, in particular, a car body attachment part for a motor vehicle

Abstract

The invention relates to a composite component and a method of producing such composite component, in particular a car body attachment part for a motor vehicle, which includes an outer skin that is defined by an outer skin foil associated with the motor vehicle. An inner layer made of plastic is applied to a rear side of the outer skin foil by providing a foamed or injection-molded backing. A mounting piece is disposed in a depression of the outer skin foil and is anchored therein. An intermediate foil is situated between the mounting piece and the outer skin foil and prevents, at least in sections, any direct contact between the mounting piece and the outer skin foil.

1. A composite component for a car body attachment part for a motor vehicle comprising:
 an outer skin that is defined by an outer skin foil associated with a vehicle; 
 an inner layer made of plastic and applied to a rear side of the outer skin foil by a foamed or injection-molded backing; 
 a mounting piece disposed in a depression of the outer skin foil and anchored therein; and 
 an intermediate foil situated between the mounting piece and the outer skin foil that prevents, at least in sections, any direct contact between the mounting piece and the outer skin foil. 
 
     
     
       2. The composite component according to  claim 1  wherein the mounting piece is surrounded by the outer skin foil at least in sections and is anchored in the depression by at least one of an interlocking and frictional fit. 
     
     
       3. The composite component according to  claim 1  wherein the mounting piece is provided with at least one anchoring projection on at least one side wall. 
     
     
       4. The composite component according to  claim 3  wherein the at least one anchoring projection is received in a respective depression of the outer skin foil. 
     
     
       5. The composite component according to  claim 1  wherein the inner layer firmly presses the outer skin foil and the intermediate foil against the mounting piece in a region of the depression. 
     
     
       6. The composite component according to  claim 1  wherein the mounting piece is a rail made from aluminum. 
     
     
       7. The composite component according to  claim 6  wherein the rail is a guide rail for a cover of a spoiler roof. 
     
     
       8. The composite component according to  claim 1  wherein the composite component is a roof module of a motor vehicle. 
     
     
       9. The composite component according to  claim 1  wherein the mounting piece is accessible from outside through an opening facing the outside and which is not covered by the outer skin foil and the intermediate foil. 
     
     
       10. The composite component according to  claim 9  wherein the opening is covered by a movable covering. 
     
     
       11. The composite component according to  claim 10  wherein the movable covering covers an edge of the intermediate foil in a region of the mounting piece. 
     
     
       12. The composite component according to  claim 10  wherein the movable covering is attached to the mounting piece by protrusions. 
     
     
       13. The composite component according to  claim 1  wherein the inner layer is reinforced with glass fiber sections. 
     
     
       14. The composite component according to  claim 1  wherein the intermediate foil is a polyethylene foil.
